I hope I can help:
The Official, Historic Definition:
“The Scriptures are and should remain the sole rule and norm of all doctrine” (Lutheran Formula of Concord, Solid Declaration, 9). “We pledge ourselves to the prophetic and apostolic writings of the Old and New Testaments as the only true norm according to which all teachers and teachings are to be judged” (Ditto, 3). “No human being’s writings dare be put on a par with it, but … everything must be subjected to it” (Ditto, 9).
“The Latin expression “sola scriptura” refers to the authority of the Holy Scriptures to serve as the sole norm (norma normans) for all that is officially confessed in the church.” (Lutheran Church - Missouri Synod at official website)
Sola Scriptura IS…
An embrace of God’s inerrent, holy, written word as the final “Rule” (staight edge) or “Canon” (measuring stick) or “norma normans” to serve as the final Standard, Plumbline as Christians evaluate positions, especially doctrine.
Sola Scriptura is NOT…
- Doctrine. It’s praxis, but yes it is an application of a doctrine - the doctrine of Scripture, which Catholics and Protestants share. Sola Scriptura applies this doctrine, but it itself is not a doctrine - it’s praxis. Thus, we need to be clear as to the doctrine part (Scripture is God’s inerrant holy written word) and the praxis part (using such as the norma normans). Sola Scriptura refers to the later.
- Hermeneutics. It is not a praxis for the intepretation of Scriptures. It’s not hermeneutics, it’s norming. Bob says Jesus was 15 feet tall (a position he may or may not have come to by the interpretation of Scriptures). Sola Scriptura addresses the norming or evaluating of that position by establishing the Rule/Canon/Norma Normans.
- Sola Toma or Sola Biblica. WHATEVER the Scripture is at that point, it is the Rule. Sola Scriptura “existed” just as much at Mt. Sinai as it does today, only the “size” of the Scripture was smaller.
- Arbitration. Obviously some process is needed to determine if the position “measures up” (arbitration) to the “measuring stick” (the Canon). Sola Scriptura does not address this issue; it only addresses the Canon issue. SOME who embrace the Rule of Scripture (Sola Scriptura) embrace private, individual arbitration (This is called “private arbitration.”) SOME that embrace Sola Scriptura embrace corporate arbitration in various forms. This is called “public arbitration.” It largely depends on whether one embraces the Holy Spirit and this process to be singular/individual or corporate/joint. But the Rule of Scripture deals with the Rule - not the arbitration according to that Rule.
- Revelation. Sola Scriptura does not affirm that all divine revelation is confined to Scripture. Indeed, Scripture itself teaches that the heavens declare the glory of God. It’s just that the praxis of Sola Scriptura does not use star gazing as the Canon for the evaluation of doctrines.
Some Notes:
- TECHNICALLY, Sola Scriptura does NOT say that all dogma must be taught in the Bible (again, remember - its a praxis and not a teaching). However, this IS a ramification of the praxis and so if often mentioned in relationship to it. If Sam taught that Jesus was 15 feet tall, it is likely it would be arbitrated that Scripture does not “norm” this - thus we’d have an unnormed teaching that we’d not regard as dogma. If Sam said that Jesus was born in Los Angeles, it is likely it would be arbitrated that Scripture reveals this to be in error and thus heresy. If Sam said that Jesus’ mother was named Mary, it is likely it would be arbitrated that Scripture norms this and it is correct. Thus, for a teaching to be normed via this praxis, it would need to be found in Scripture *to a suffient degree *to be likely so arbitrated. Because this ramification is rather clear, it is sometimes mentioned in connection with the praxis - but it’s not technically a part of it.
- The Doctrine of Scripture says that SCRIPTURE is inerrant. The praxis of Sola Scriptura does not say that every use of such will be infallible. I may have a perfect hammer but it doesn’t guarentee that I will make a perfect table. But it probably is better than using my finger.
In the next post, I’ll share some quotes just to clarify the definition.
I hope that helps.
